ARM: OMAP2+: clock: add support for specific CM ops to ti_clk_ll_ops
Clock driver requires access to some CM API functions once the code is being moved under the clock driver from the platform directory. Gate type clock requires access to cm_wait_module_ready and cm_split_idlest_reg functions, which are both used for waiting until the module being clocked has been successfully activated. These CM APIs are now exported through the ti_clk_ll_ops struct. Signed-off-by: Tero Kristo <t-kristo@ti.com>
